IMPROVEMENT IN JOURNAL-BEARINGS FOR HARVESTERS.

Specification forming part of Letters Patent No. 159,758, dated February16, 1875; application filed August 12, 1874.

To all whom it may concern:

Be it known that I, EPHRAIM F. HERRING- TON, of West Hoosick, in thecounty ofltensselaer and State of New York, have invented a new andImproved Method of Securing the J ournal-Bearings of Harvesters, ofwhich the following is a specification:

My invention relates more especially to what are known as iron-frameharvesters. In such machines one customary way of securingjournal-bearings is to turn a thimble accurately to receive the shaft,and to drive this thimble into a hole in the frame, the hole also havingto be bored out to receive the thimble. This troublesome and expensiveprocess is necessary in order to secure the proper alignment of theshaft and the correct meshing of the gears.

Now, it is the object of my invention to obviate the objection incidentto the above-described method, and to secure the correct engagement ofthe gears by a cheap, simple, and expeditious process; to which ends myimprovement consists in a novel method of adjusting the journal-bearingin its proper position in the frame, and securing it there by pouring ina readily-fusible metal or alloy, which can readily be melted out shouldthe removal or replacement of the shaft become necessary.

The accompanying improved process.

Figure 1 represents a transverse section through a portion of the frame,journal-box, and shaft, placed in position for castingin the fusiblealloy or metal Fig. 2, a longitudinal section thereof. Figs. 3 and 4show the journal box secured in place.

The portions A of the frame, in which the journal-boxes B are to beinserted, are provided with holes or openings considerably larger thanthe outside diameter of said jourdrawings illustrate my rial-boxes.Lips, holes, or studs a are also provided to prevent the turning of thealloy in the frame. The journal-box is made polygonal in form, orpILVIdBd ithridgempins or, studs IMMHILMPQB. The gears are firstinountedon their respective shafts, and

made to mesh properly. The boxes B are then slipped on the shafts O,placed in their proper bearings in the holes of the frames, and held byany suitable means. The soft metal or' fusible alloy Dsuch, forinstance, as lead or Babbitt metal-is then poured around the boxes,filling the space between the boxes and the frame, thus setting theshaft and gears accurately in position. Should the boxes become worn thealloy can be fused and the box removed and replaced by another, whichmay be cast in by pouring the alloy in, as before.

Fig. 3 shows the position of the box when the parts are all in line,while Fig. 4illustrates the manner in which the box may be adjusted tocompensate warping of the frame or other distortions.

I do not broadly claim casting a box in place, as cast-iron has been soused; but this sometimes melts the frame or box, or runs together withit, so as to prevent any subsequent removal of the box.

I claim- The method herein the journ al-boxes ofharvesters in their frames, I which consists in adjusting the position of the 5 box by means ofthe gears and shafts, audit then casting readily-fusible metal or analloyil between the box and frame.

In testimony whereof I have hereunto subscribed my name.
